To all whom it may concern:

Be it known that we, ANGELO SCHIEPPATI, of Foro Bonaparte 25, Milan, Italy, and Enoanno IZAR, of In veruno, Italy, have invented certain new and useful Improvements in Vehicles with Portable Foundations for the Wheels; and we do hereby declare the following to bea full, clear, and exact description of the same.

The vehicle, which forms the subject matter of the present invention, and which will be hereinafter called a sledge wagon, is shown in the accompanying drawing wherein 1 Figure 1 shows a side elevation, Fig. 2 a section corresponding to the line yy of Fig. 1, Figs. 3 and 4 a Support seen from the front and the side, Figs. 5 and 6 each a detail view of the connection of the supports with one another, Fig. 7 a detail view of a block, and Fig. 8 a section on the line :c:c, Fig. 7.

Each sledge wagon has two or more blocks A, which are of the form shown in the drawing or any other similar form. They may be in twos as in the special case of i the drawing, or also in threes or fours and incidentally have the cross section of an ellipse, which is flattened I on one side. Upon the upper surface of these blocks glide the wheels and for this reason the upper surface must'be perfectly smooth, without any projections or the like whatever. The blocks consist of wood with a metal sheathing or of metal only or other suitable material. I

The blocks may ,be either rigidly connected with one another, as in the particularcase here drawn, where a beam B is located between them, (Fig. 2) or they may be also independent of one another. In the present case the bed of the wagon rests by means of the bearer 0 upon the beam B, so that in this way the frame of the wagon is supported.

A series of supports or shoes, D, which are joined up inti) an endless chain and each of which carries a pair of wheels of steel or other siiitable material, surrounds each block A. The wheels rotate about a fixed point of rotation which is present on each support or shoe and which may be formed by a transverse shaft or rod, as at p, upon which the wheels turn freely, the relative arrangement and construction being preferably such that the wheels have also a lateral play or movement upon the shaft. When the wagon moves therefore each pair of wheels comes in contact with the surface of the block A.

Figs. 1 and 2 show the arrangement described clearly and it will be seen therefrom that the supports of the chain which are located underneath the block A, bear the entire load. The supports D with the wheels 1' belonging thereto, are shown in Figs. 3 and 4 from which it will be seen that the wheels rotate about fixed points of rotation between grooves. These grooves are made in the supports themselves. Each of them car pair of smallplates, which are provided with an opening. These parts serve to connect the supports with one another. The supports may consist entirely of hardwood and be partially sheathed'with metal or they may also consist of metal or other suitable material. The supports and theirwheels 'r are of course sufficiently strong to bear the entire load.

- For connecting the supports with one another the ar rangement which is shown in Figs. 5 and 6 is very convenient. A strong metal bar traverses the holes in the small plates 0. The interior space of the elongated ring f is so proportioned that the bars cannot come out of these rings. tagc that when the wagon has to pass round a curve the the direction of movement. 1

It should be remarked that where the streets are crooked and irregular the supports when they come in contact with the ground must fit themselves thereto, whereby the parallelism which they had with the lower flattened portion up to this point would be lost. From this would follow that one wheel of each support which tact with the flattened lower portion of the block and support, whereby naturally the danger ofthe axles breaking would be greatly increased. To obviate this evil, the blocks or side pieces A are made movable in such a manner that their flattened portion may always be kept parallel with the ground, and resttherefore upon all the rollers that are in contact with the ground.

This is obtained by dividing block or side piece A into two parts a and b of which a is fixed, and b is movable,

being connected with said part a by a shaft or pivot m,

so that it is free to rotate and adjust itself parallel thereto on precipitous ground.

I with portable foundation for the wheels have been made, with side piecesor blocks running over an endless chain of wheels supported by shoes or guards gliding over the ground. We therefore do not claim such a combination broadly.

desire to secure by Letters Patent:
